4 Way IP40 Metal Enclosure – For MCBs & RCBOs (WME04)
The WME04 is a 4-way IP40 metal enclosure for housing suitable MCBs, RCBOs and other DIN-rail devices in an indoor circuit-protection assembly. It measures 130 × 240 × 112mm (W × H × D) and is supplied with a raised DIN rail, neutral terminal bar and earth terminal bar.At 130mm...
Read full descriptionThe WME04 is a 4-way IP40 metal enclosure for housing suitable MCBs, RCBOs and other DIN-rail devices in an indoor circuit-protection assembly. It measures 130 × 240 × 112mm (W × H × D) and is supplied with a raised DIN rail, neutral terminal bar and earth terminal bar.
At 130mm wide, this is the narrowest option in the standard four- to twenty-two-way WME range below. Check device depth, terminal access and cable space when planning a compact assembly.
Supplied enclosure features
- 4-module enclosure format
- Non-combustible metal construction with polyester powder coating
- IP40 protection for suitable indoor locations
- Raised DIN rail for cable routing
- Neutral and earth terminal bars
- 25mm and 32mm nominal cable-entry knockouts on the top and bottom
- 40mm side knockouts and larger rear cable-entry slots
- Raised keyhole mounting points, spirit level and captive cover screws
Planning the assembly
This is an enclosure listing, supplied for fitting the required circuit devices. The stated way count describes the enclosure format; it is not a promise of the same number of spare outgoing circuits after a main switch, SPD or other equipment is installed.
Check the combined device width, depth, terminal positions, wiring space and compatibility of the complete assembly. A matching modular width alone does not establish that a device or busbar is suitable.

What is supplied with this enclosure?
The metal enclosure is supplied with a raised DIN rail, neutral and earth terminal bars, a spirit level and captive cover screws. Select the circuit devices for the intended assembly. For an interconnecting busbar or other accessories, check the supplied pack and compatible parts with Power & Data UK.
Does the way count mean the same number of outgoing circuits?
No. WME04 is a 4-way / 4-module enclosure format. Allow for any incoming switch, SPD or other fitted equipment when calculating the remaining outgoing-circuit space.
Will every MCB or RCBO fit?
Check the exact devices and complete assembly. Modular width is only one consideration; depth, terminals, connections, wiring space and manufacturer compatibility also matter.
What are the dimensions?
WME04 measures 130 × 240 × 112mm, in width × height × depth order.
Can it be used outdoors?
No. WCED specifies IP40 for indoor use. Choose an enclosure with protection appropriate for the installation environment.
Does the enclosure alone make the installation compliant?
No. WCED identifies BS EN 61439-3 for the enclosure range. The fitted devices, connections and complete installation still need to meet their applicable requirements.

Device selection, outgoing-circuit capacity and electrical ratings must be established for the completed assembly. The enclosure format alone does not specify those ratings.
Install in a suitable indoor location using the raised keyhole mounting points and fixings appropriate for the mounting surface. Plan the device layout and cable routes before opening the required knockouts. Protect cable insulation at entry points and maintain the enclosure's IP40 protection.
Check device compatibility, enclosure earthing, terminal access and the cable space required by the completed assembly. Follow the supplied instructions for each terminal and fitted device, including conductor preparation and tightening torque. A qualified electrician should assemble, inspect and test the installation before energising.
